The IC3603A177AF2 is a relay created by General Electric for the Mark I and Mark II series. A relay is an electrical device, typically incorporating an electromagnet, that is activated by a current or signal in one circuit to open or close another circuit. Relays are used where it is necessary to control a circuit by a separate low power signal, or where several circuits must be controlled by one signal. The IC3603A177AF2 has a faceplate that has the screw ports numbers, the part number (IC3603A177AF2), and General Electric’s company insignia printed on it. This faceplate is secured on with two screws. The IC3603A177AF2 has two thin metal edges with holes in each corner to secure the IC3603A177AF2 into place. The screws are labeled one through twelve (1-12) and can control up to twelve circuits. The IC3603A177AF2 is a black rectangular box with twelve golden flathead screws. Each screw is separated by a grey divider and is indented to fit the screw along with a metal eye ring underneath the screw. The screw ports are used to attach wires to connect which circuits the relay needs to control. There are four square holes one in each corner of the IC3603A177AF2.
